Efficient High Gain 100 to 300 MHz Horn Antenna

A quad petal wide band horn is proposed with improvements over prior similar designs to meet all the requirements of the solicitiation. The horn offers dual independant polarizations with high cross pol. isolation so the antenna does not need to be rotated for multi-pol. measurements. The improvements help to minimized back and side lobes while meeting the high gain requirements. The horn is made of light weight materials resulting in a unit weight potentially less that 30 pounds and volume 1/9th of the solicitation's allowable volume. The horn may be arrayed to provide in excess of 30 dBi of gain at cutoff while adding the unique feature of being able to generate nulls on high multipath scatters that could cause interference problems.
